Definitions

  • the present invention relates to the field of communication, and more particularly, to a resource and admission control method applied to nomadicity and wholesale scenarios.
  • next generation network which is one of hotspot research subjects in the current communication standard field, uses the Internet protocol (IP) packet technology as a bearer network technology and integrates with fixed communication and mobile communication so as to provide more abundant multimedia services, such as emerging services having real-time requirements (IP television, video conference, multimedia distance education, video on demand, etc.), which require that a communication network should be able to provide support for high efficient end-to-end Quality of Service (QoS). Meanwhile, users' requirements for network Quality of Service are higher and higher. Therefore, how to provide the end-to-end QoS will be one of core problems of the NGN.
  • IP Internet protocol
  • QoS Quality of Service
  • the International Telecommunication Union-Telecommunication Standardization Sector (ITU-T), which is the telecommunication standardization sector of the International Telecommunication Union (ITU), has constituted a standard regarding to resource and admission control.
  • ITU-T The International Telecommunication Union-Telecommunication Standardization Sector
  • RCF resource and admission control function
  • PD-FE policy decision functional entity
  • TRC-FE transport resource control functional entity
  • the TRC-FE interacts with a transport function through an Rc interface and interacts with a transport resource enforcement functional entity (TRE-FE) through an Rn interface; whereas the PD-FE interacts with the TRC-FE through an Rt interface, interacts with a customer premises network (CPN) through an Rh interface, interacts with a policy enforcement functional entity (PE-FE) through an Rw interface, interacts with a service control function (SCF) in a service layer through an Rs interface, interacts with a network attachment control function (NACF) through an Ru interface, and interacts with other next generation networks through an Ri interface.
  • TRE-FE transport resource enforcement functional entity
  • Rn transport resource enforcement functional entity
  • PE-FE policy enforcement functional entity
  • SCF service control function
  • NACF network attachment control function
  • the PD-FE is independent of both the transport technology and the SCF, and makes a final decision of resource and admission control based on network policy rules, service information provided by the SCF, transport layer subscription information provided by the NACF and resource availability decision results provided by the TRC-FE.
  • the TRC-FE is independent of services, but is associated with the transport technology.
  • the TRC-FE is responsible for collecting and maintaining transport network information and resource state information. After receiving a resource request from the PD-FE, the TRC-FE performs resource-based admission and control based on the QoS, priority requirements, resource availability information and transport-related policy rules.
  • the transport layer is comprised of a policy enforcement functional entity (PE-FE) and a transport resource enforcement functional entity (TRE-FE).
  • PE-FE performs policy rules sent down by the PD-FE.
  • the PE-FE which is a packet to packet gateway, may be located between a customer premises network (CPN) and an access network, between an access network and a core network, or between different operator networks, and is a key node for supporting dynamic QoS control, port address translation control and network address translation (NAT) traversal.
  • the TRE-FE performs transport resource policy rules sent down by the TRC-FE, and their scope and functions and the Rn interface remain to be further studied and are not within the research scope of the R2 stage.
  • a diagram of a RACF nomadicity scenario is given, as shown in FIG. 2 .
  • a SCF belongs to a NGN home operator and interacts with a PD-FE of the NGN home operator.
  • the PD-FE of the NGN home operator interacts with a PD-FE of a NGN visit operator through an Ri interface;
  • PD-FE interacts with PE-FE and TRC-FE in its network through an Rw interface and an Rt interface, respectively.
  • a diagram of a RACF wholesale scenario is given, as shown in FIG. 3 .
  • a SCF belongs to a NGN retail service provider that is generally an actual service provider.
  • a PD-FE of the NGN retail service provider interacts with a PD-FE of the NGN wholesale service provider that is generally a network operator through an Ri interface.
  • the network operator uses a network level as infrastructure for opening to multiple service providers in a wholesale way and does not provide services; whereas the service provider provides various services.
  • users are in this scenario, they access networks via a network of the network operator to visit the networks and enjoy the services provided by the service providers.
  • PD-FEs of the NGN home operator and the NGN retail service provider will be denoted by PD-FE(H); PE-FEs of the NGN home operator and the NGN retail service provider will be denoted by PE-FE(H); PD-FEs of the NGN visit operator and the NGN wholesale service provider will be denoted by PD-FE(V); PE-FEs of the NGN visit operator and the NGN wholesale service provider will be denoted by PE-FE(V); and TRC-FEs of the NGN visit operator and the NGN wholesale service provider will be denoted by TRC-FE(V).
